Application filed March 19, 1919. Serial No. 283,643.

(FILED UNDER THE ACT F MARCH 3, 1883, 22 STAT. L., 625.)

` the following is a specification.

The inventiondescribed herein may be used by the Government, or any of its othcers or employees, in prosecution of work for the Government, or by any other person in the United States, without payment of any royalty thereon.

y This invention relates to building units, and has for one of its objects to improve the construction and increase the efliciency and utility of devices of this character.

Another object of the invention is to pron vide a combined binding device for each unit and a filler device between the units whereby the joints are rendered air and moisture proof, and likewise germ and vermin proof.

Another object of the invention is to provide a binding and protecting element for the sectional vunits which operate to protect the edges of the units and enable themr to be quickly assembled when required.

l/Vith these and other objects in view the invention consists in certain newV and useful improvements hereinafter described and specifically set forth in the claims, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 1 is a plan View of a plurality of floor sections constructed in accordance with the invention.

Fig. 2 is a section on the line Fig. 1.

Fig. 3 is a detached perspective view of a portion of one of the combined binding and packing members.

Fig. 4 is a section of one of the blanks from which the packing strips are formed.

The improved unit is represented as a whole at 10 and the units are intended to be arranged side by side and end to end. Each unit is preferably constructed of tongued and grooved material connected in any suitable manner. The units may beof any required dimensions to correspond with size of the building.

Disposed over the edges of the units are combined binding and packing or germ ei;- cluding devices lof sheet metal or other suitable material. rJ'lie binding devices are initially bent into channel shape transversely, each including a main web 11 and spaced apart longitudinal flanges 19.-'13. The binder members are applied to each edge of each section with the flanges 12-13 mitered at the corners as indicated in Eig. 1. The'flange 13 of each binder member of two of the edges of each section are of greater width than the other flange and bent upon itself longitudinally to form an additional web 15, andk extended obliquely to the main web 11, as shown.

By this arrangement the spaces between the units are occupied by two thicknesses of the packing material, with elongated V- shaped spaces opening outwardly between the confronting edges of the Yunits. The obliquely directed web members 15 form yieldable packing members between the units. The Vshaped cavities thus formed are preferably filled with a suitable cement or other packing material. If preferred, the filler material may be oakum or like ma terial either alone by itself or mixed with a suitable compound to render it waterproof.

The joints between the units are thus rendered moisture and germ proof, and this feature of the invention is essential, especially when the structure is employed for hospital and like purposes.

Attached to the inner face of each unit is a layer of suitable covering material, preferably the material commonly known as wall board, indicated at 16. Each section of the covering material is formed of superposed layers of paper and cement rolled or otherwisecompressed to render them sufficiently hard to withstand the wear and friction incident to their use.

At their edges the flanges overlap the covering material 16 and after the parts are in position the free edges of the flanges 12 and the folded portions of the flanges 13 are crimped inwardly and pressed into the material 16, as shown at 111, thereby securing the parts in relative position and likewise forming a uniform face on the whole structure, and obviating the production of ridges at the junctures of the units.

Having thus described the invention what' is desired to secure by Letters Patent is:

1. In a building structure a plurality of units adapted to be arranged end to end and edge to edge, and combined binding and packing devices substantially in channel shape transverselyy and bearing byV their flanges over the edges of the units, one of said flanges being of increased Width and bent upon itself and extended in proximity tothe binding and packing device of an adlateral llanges in spaced relation to engage jacent unit.,

.2. A packing'and binding' device form-ed of a continuous sheet of material consisting of lateral flanges connected by a Web one of said flanges being extended and bent back Vupon itself with its projecting end lying in proximate inclined relation tothe Web.

3. A combined bindingl and packing device comprising a member channel shaped transversely and including a main web and Y lateral flanges in spaced relation, one of said flanges being extended to. form a supplemental Web directed initially oblique to the main Web and extended in yproximity thereto.

4. A combined bindingl and packing device comprising a member channel shaped transversely and including a main web and lateral flanges in spaced relation, one of said flanges beingY of increased Width and bent upon itself andl extended to lforml a supplemental web directed initially oblique to the main Weband extended in proximity thereto. i 5. AThe combination with a building unit of a combined binding 'and packing device comprising armember channel shaped transversely and including a vmain Web and over the edges -o Vthe units,KV one yof said flanges being extended to form a supplemental web directed -ritially oblique to the main Web and extended iny proximity thereto and adapted tocontact 'with the malin web. of theA binding and packing device of the adjacent unit. A

6. A building structure in a plurality of units adapted tov be arranged end to end and' Y edge to. edge, combined binding and packing devices substantially .in channel shape transversely and bearing by their flanges over the edges of the. units, one of saidV flanges being of increased Width and bent kupon itself and extended obliquely te the binding and packing device of the adjacent unitto Vform Vshaped cavities between the units, and va filler of compressible material in said cavities.
